FIREARM,

Application filed December 13, 1919. Serial 1\To. 34,4,677.v

To all wlw/m. t may concern i Be it known that l, JOHN D. PEDnRsEN, acitizen of the United States, residing in Jackson, in the county ofLincoln and State of lllyoming, -have invented certain new and usefulImprovements in Firearms, of which the following is aspecification.

rllhis invention relates more especially to fire-control mechanisms foruse in auto-loading small-arms, and more particularly to that class ofsuch mechanisms which is illustrated and described in my Patent No.1,348,733, dated'August 3, 1920, filed July 17, 1919. A principal objectof the present improvements is to provide an organization of firecontrolmechanism in which the operation of certain of the coacting membersshall be more simple in character, and'in which an improved safety-gripcontrol shall be coactive with firing-train and its associated devices,further objects and advanf tages are hereinafter explained in the courseof the description. Y

, Certain of the principal features of my present improvements are shownin Figs. 80, V81, 82 and 83 kofl said patent, in which I these featureslare described asta modiiication that is within the scope of claimstherein broadly defined. In this present application, however, certainof the details of the mechanism, shown in said views of said priorapplication, in a more simple form,are further improved in constructionand arrangement, andare also employed in new combinations not disclosedin said prior appli. cation.

In the accompanying drawings forming a part of this specication, Figure1, is a side view, and Fig. 2 an end vien7 (as seen from'theright-'handinFig 1), of one kind 1 of auto-loading pistols to which mypresent improvements are applicable; 'these two views correspond,respectively, with Figs.' 1 and Q of said patent.

VFig. 3, is a. side view, on an enlarged scale, ofthe rearward portionof the pistol, the

forwardend being omitted, and the frame shown broken away forillustrating the interior mechanism; this view corresponds, in largepart, with Fig. 3 of 'said patent, in which the various operable partsnot restricted to the present invention, are more fully illustrated anddescribed. n

Fig. 4;, is a horizontal section,in plan view, of the rear portion ofthe pistol on the line el-fi of Fig. 3, with the sliding breechaction ofthe pistol removed, and 'showing A i the pistol locked by the slidablemember or controller, the hammer and searlocked, the trigger member outof contact with the disconnector located between it andthe sear,

and the sear in contact with said disconnector and out 0f contact withsaid controller.I

Fig. 6, is a side view of the rear endI portion of the pistol showingpartsof my fire control mechanism, the hammer being in'fring'position,the sliding `breechaction locked by said controller, the hammer and searlocked, the trigger member, preparatory to firing, in contact with saiddisconnector and out of contact with said controller. f

f Fig. 7, is a side view of aV portion of the rear end ofthe pistolshowing parts of my fire control mechanism, the hammer being in firedposition, the breechaction unlocked from the slidable controller, thehammer and Sear unlocked, the trigger-member, afterniring, in contactwithsaid disconnector, and

the sear out of contact with said disconnector and in contact with saidcontroller.

Fig. S, is a side viewfof the rear portion ofthe pistol sh'owingfthebreechact-ioili moved rearwardly to cock the pistol and unlock from the"controller, lthe hammer vbeing in` course of movement to firing posi'-tion and not yet positively engaged with the sear, the trigger-memberbeing in contact with Said' disconnector prior to forward movement ofthe trigger-member', andthe if! sear in contact lwith said disconnectorand out of contact with said controller.

Similar reference characters or numerals refer to similar partsthroughout the several views.'Y i i f l My fire control mechanismcomprises,to gether with the various parts hereinafter described, afiring member or hammer H,

movable to firing vposition and to fired posiv tion. The firing memberor hammerl in the present embodiment of my invention is moved to firingor cocked position by 4enga ement'therewith of a roller 3, on the c. sliing breechaction or mainY slide C of tho pistol, as the slidingbreechaction or mainslide C is moved rearwardlywhen the pistol isdischarged. The firing member or hammer H is provided with afiring-notch or cock-notch 8j and an eccentric cam face 8k.

A The Sear member S is provided with a locking shoulder 17b for engagingthe cocknotch 8i, and with a face 17, for engaging the eccentric camface v8k of the tiring member or hammer H, and with arms 17f, only oneof which arms is shown in the views, for engaging the slidablemember orcontroller The sear member S is provided with a downwardly extendingportion which af- 'fords a face 17e for engagement therewith of acontactor, and with an end 17 d which. engages a disconnector, suchcontactor and such disconnector being hereinafter described.

The slidable member or controller N is movable upwardly and downwardlybetween slide-faces 15 and 16, formed in the frame and grip-stock of thepistol. rl`he slidable member or controller N has at its upper end aprojecting portion or end 14d which is engageable with the slidingbreech action of the pistol when the slidable member or controller N isin upward position, to prevent rearward` movement of the sliding breechaction. v

The slidable member or controller N is provided'with a shoulder 141having upper engaging surfaces 14e with which the arms 1-7b of the searmember S are engageable, and at its lower end is provided with a recess17 'to receive the 'upper end of the actuator 14m, hereinafterdescribed. The slidable ,l member or controller N has at its lower endend-faces or' bottom-faces 14.-

The actuator14m, the purpose of which is to move the slidable member orcontroller N upwardly, comprises a plug or nose-piece .18 having a stem19, which is seated at its lower end in a bracket formed in thegrip-stock of the pistol, the plug or nose-piece 18 being movable orslidable upwardlyY and downwardly in the recess 17 ofthe slidable memberor controller N, and in a recessed or bored member 17, formed in thegrip-stock of the pistol, the plug or nose-piece 18 never being entirelyretractable from the recess 17, and by its engagement with said vrecessv17, and with said recessed or bored member 17 Vproviding a means forpreventing inward shifting of the lower end of the slidable member orcontroller N. But I do not restrict myself to this means for preventingsuch inward shifting, as any suitable means for this purpose may beused.

The disconnector la is `pivotally movable and comprises a base or block19, which is pivotally attached toV the slidable member or controller N,and a stem 20. The stem 20 vhas an outer or frontl face 21- and an upperend-face 22, and an inner or rear face 23.

The end of the trigger member F is engageable with said front face 21when the firing member or hammer .H is in firing position, and isengageable with said end-face 22, when the liring member or hammer H isin fired position, and the end 17d of the sear member Sis engageablewith said rearv face 23 when the firing member or hammer is in tiringposition. The stem 20 thus lies between the trigger member F andthe-Sear member S. Y

The trigger member F isv movable forf wardly by means not shown, and. bypull thereon is movable rearwardly. The trigger member F is providedwith anrend 6s conssting of an end-face and an adjacent curved face, theend-face being intended to engage the outer face 21 of the stemY of thedisconnector lo when the firing member or hammer H 1s in nring positionand the sliding memj of said disconnector when the firing member *Y orhammer H is in lired position and the disconnector le has moveddownwardly with the downward movement of the slidable member-orcontroller N. Y

My lire control mechanism is provided with `a grip-safety-portion ordevice, generally denoted by Gr, which comprises ka gri operable memberor grip-,safety member GP. The grip-safety member G is hand compressibleor yieldable, and is pivoted to the grip-stock of the pistol by means ofa pivotpin g, preferably in the manner described and set forth in mySaid patent. 1

The gripsafety member G closesthe slot or space 2S formed in thegrip-stock of the pistol and which slot orspace is of usein assemblingthe details of my invention.

The top portion ofthe grip-safety member G is slotted out to furnishclearance for the liring member or hammer H and the sear y member S,leaving a pair of side walls 7e which are extended to provide a pair oflocking-prongs 7b. When the end (i2` of the gripsafety member G is inrearward position, or position of safety, the locking-prongs orlever-arms 7b are immediately below the endfaces or i' bottom-faces 14fof the slidable member or controller N which is thereby locked againstdownward movement.y The contactor, 2/1, is carried by the grip-safetymember and is in engagement with the Searv member S whether thegrip-safety member is in position of safety or compressed. The contactor24, consists of a point or nose-piece 25, which isv moved or pushedoutwardlyv engagement with the face 17e of the Sear j member, andthereby hold the lower end 17d of the sear member in contact orengagement' with the inner or rear face 23 of the disconnector la whenthe ring member or hammer H is in firing position and the grip-safetyme-mber G is in position of safety.

5 The tiring spring 8e, or spring for actuating the tiring member orhammer H, is seated in the grip-stock adjacent lto the lower end of thegrip-Safety member G', preferably in the manner described in my 0 lastabove-mentioned co-pending application, the pressure of the spring 8ebeing upward. A cupped member or cupped plunger 8", which is movable orslides betweena side-face formed in the Grip-stock of the 5 pistol andthe grip-safety member Gr', af-

fords an abutment for the spring 8e, the movable member or plunger 8Cthus engaging in its movement the grip-safety member G.

A rod 8b is pivotally attached at its upper end to the tiring member o rhammer H, and has a rounded lower end which is seated in the cuppedportion of the movable member or plunger 8c.

5 In operation, Figs. 3 and 5, the sliding breech-action of the pistolbeing in forward position, is locked in this position by engagementtherewith of the slidable .member or controller N which is held inupward or locking position by the locking prongs 7b of the grip-safetymember Gr, the slidable member having been moved upwardly by theactuator 14m.

The firing member or hammer H having 5 been moved to firing position, islocked in this position by the sear member S, the, lower end'ot which isin contact or engagement with the disconnector lc, being held -in thisposition by the contacter 24. The trig- 0 ger member F is in'contactwith disconnector 7o. preparatory vto rearward pull on the triggermember, and the grip-safety member G is in rearward position, orposition of safety. Theslidable member or control- 5 ler N when inupward position thus locks the sliding breech action ofthe pistol andlocks the sear member and tiring member .or hammer in tiring position.

Grip-compression of the grip-safety mem- 0 ber G', Figs. 7 and 8,releases the lockingprongs 7b kthereof from engagement with the slidablemember or controller N to permit downwardimovement thereof. Iull on thetrigger member F moves'the disconnec- 5 .tor le inwardly and therebymoves the sear member S, to release the firing member or hammerI-I formovement to fire-d position by the spring 8c, the arms 17 f of the searmember engaging or bearing down upon the 0 uppei1 surfaces of theshoulder 14p ofthe slidable member or controller N, as the iiring memberor hammer H is moved to fired position, to move the slidable member orcontroller downwardly and out of locking 5 position. Pull on the triggermember F also causes this end of the trigger member to engage or ride upon the upper end of theA disconnector lo while the curved face of theend of the trigger member F engages the adjacent side face of thedisconnector k and assists in overcoming the pressure oi' the spring ofthe actuator 14m to afford downward movement of the slidable member orcontroller N.

Release of grip-compression ofthe gripsafety member G returns thegrip-safety member G to position of safety and the various other partsof my invention to the position shown in Figs. 3 and 5, and abovedescribed. Y Y
